Malachi 3:7-8; Malachi 3:13

7From the days of your fathers you have turned aside from my statutes and have not kept them. Return to me, and I will return to you, says the LORD of hosts. But you say, 'How shall we return?'8Will man rob God? Yet you are robbing me. But you say, 'How have we robbed you?'In your tithes and contributions.
